BROADCAST SEED-SOWER.

SPECFICATXON forming part of Letters Patent No. 462,341, dated. November3, 189] Application filed February 14, 1891. Serial No. 381,505. (NomodelJ To @ZZ whom it' may concern:

3e it known that I, PnRcIvAL V. WAD- LEIGH, a citizen of the UnitedStates, residing at vest Superior, in the county of Douglas and State oflVisconsin, have invented a new and usefulv Broadcast Seeder and Marker,of which the following is a specification.

My invention has for its object the provision of means by which seed maybe readily conned and spread uniformly over a wide area automatically inthe advance of the machine and by which a line may be marked in theforward travel of the machine to serve as a guide for the operator.

My invention consists in a suitable supporting-carriage, on which islocated a seedcontaining boX, into which open tubularseedconveyers,which latter when in operation are extended on each side of thecarriage, approximately at right angles thereto, these. tubes being heldor fixed to the seed-containing box by means of a flexible o1' universalelbow-joint, so that the conveyers may bear- `ranged upon the carriagein transportation.

Openings are provided at intervals along the conveyers, at which pointsthe feedcups are attached and within which the predetermined amount ofgrain .is delivered from the conveyer-tubes into the scattering-spouts,at the lower end ot' which scatterer-disks arelocated, said feeds beingrotated in the cups initially from one point of operation andregulatedin order to meet the Various requirements, the amount of feedbeing determined by a scale.

My invention consists, further, in certain details of construction,hereinafter to be described, reference being had to the accompanyingdrawings, in which- Figure l is a rear View of the supportingcarriage,showing the seed-box in elevation and also the conveyor-tubes. Fig. 2 isa detail view of one of the seed-cups. Figs. Sand 4 represent detailviews of the two parts of the seed-wheels. Fig. 5 is alike View showingthe said two parts joined. Fig. (5 is a detail sectional view of theseed-wheels within the fecdcups. Fig. 7 .is a detail view of thescattering-spout. Figs. 8, 9, and lO are details of the parts forregulating the feed of grain and indicating the amount of feed. Fig. llis a plan view of the supporting-carriage, showing the drive-gear. Fig.l2 is an enlarged view of the regulating and indicating device shownapplied.

Adesignates theseed-containinghox,\\'l1ich, as shown, is mounted upon asuitable supporting-carriage. with a hopper-bottom, as indicated by thedotted lines, Fig. l.

B B are seed-conveying tubes, which open into the seed-box A andarefixed thereto, being held inv an inclined position by means of staysB2 B2, secured to the seed-box A, the inclination being from the saidbox to the outer ends of the said conveyers B B, so that the seed shallnormally tend to travel to the extreme end of the conveyers. Atintervals on the lower side of the said conveyers B B are openings, atwhich points the seed-cups C C (shown in detail in Fig. 2) are secured,v

said cups consisting of the saddle a., the tilbular portion ct, and thedischarge-spout d.

The feed-wheels, Figs. b', l, and 5, are in two parts D and E, theformer having a square axial longitudinal perforation, through which theactuating rod or shaft FP rotates, as hereinafter described, said part Dbeing held in place rigidly within the feed-cups C C by means of acollar Z). The counterpart E also has acentral longitudinalperforatiomthro ugh which said rod or shaft E2 passes, this counterpartE being keyed to said shaft E2. The ngers d of the two parts D and E areadapted to intermesh, as shown in Fig. 5. The actuating rod or shaft E2is driven in the following manner:

Secured to one of the wheels of thesupportingecarriage is asprocket-wheel Il, Fig. 2, which latter is connected with asprocketwheel H2, mounted loosely on the end of a counter-shaft'llS, thelatter being mounted ou bearings on the carriage. Also mounted looselyon the said counter-shaft H3 are the sprocket-wheels J and J 2, whichare provided with the parts of a clutch at their hubs d (1..

K are rods connecting the ends of the levers J:S with the bell-cranklevers F2, the lat.- ter being respectively connected to the handleversL2 and L3.

Referring now to the device for regulating and determining the feed,(shown in Figs. 9,10, and 11,) M is an indeX-plate, which is secured tothe conveyer-tubes preferably at a point The seed-box A `is formed IOOintermediate of the ends of said conveyertubes. M2 is a slotted plateadapted to be secured to the under side of the conveyer at the pointwhere the index-plate M islocated, said all times.

plate M having a connecting-screw m traveling in the slot therein. M3 isa three-sided frame, which is mounted upon the shaft E2 and held inposition thereon by means of collars m m. The said frame M3 carries theindex-finger N, which being in a vertical position and the frame beingfixed on said shaft E2 at the point of attachment of the indexplates Mthe said index-finger is adapted to assume varying positions on thescale of the plate. The upper part of frame M3 is perforated at fm,screw-threaded, and thus adapted to receive the connecting-screw m. N2are scattering-spouts fixed at intervals along the conveyer-tubes B B,located at the seed-cups C C t0 receive the grain therefrom. N3 arescattering-disks located at and secured tothe lower ends of the spoutsN2. These spouts vary in length as they approach the extremities of theconveyer-tubes. S is alaterallyextending arm carrying at one end themarker-wheel Nfl, secured to the upright on the supporting-carriage.

The operation of my invention is as follows: In the forward travel ofthe carriage, assuming the sprocket-wheels H2, J, and J2 to be in gearwith the counter-shaft H3, the shafts or rods E2 on each side of thecarriage are rotated. The grain is being constantly fed for the wholelength of the conveyer-tubesB B, 'so that the latter are within thegrain-cups at The part of the feed-wheels D being xed within theseed-cups rotates with the shaft E2, but has no capability of lateralmovement, Whilethe partE rotates with said shaft, and also has alateraladjustment thereon. The fingersdof the two parts,intermesh ing, formpockets filled in by the grain, and in the rotation of the feed-wheelson shaft E2 this grain is deposited in the scattering-spouts N2, isdiverted broadcast, and in its travel through the'spouts is protectedfro m'the wind'. The operator may adjust the feed-wheels and regulatethe amount of grain fed by lateral movement of the shafts E2, the fingerN indicating on the index-plate M the amount of l. In abroadcast-seeder, the combination of a seed-box, conveyer-tubes securedto and opening therein, feed-wheels adapted to be adjusted to regulatethe feed, and means for determining the amount of feed, shafts rotatedby the advance of the carriage operating the feed-wheels, and levers andconnections by which the entire machine may be caused to cease operationor either one of said conveyers caused to cease operation, andscattering-spouts leading from the feed-Wheels to the ground, togetherwith scattering-disks located at and secured to the ends of thescattering-spouts, as and for the purposes set forth.

2. In a broadcast-seeder, the combination of a supporting-carriage, afeed-box located thereon, a pair of inclined conVeyer-tubes opening intoand extending from the seedbox on each side of the carriage, a pluralityof spouts extending vertically downward from said conveyers anddiminishing in length on approaching the` extremities thereof, seedcupssecured to the conveyer, said seed-cups opening into said spouts,feed-wheels operated by rotated shafts with said cups, means forregulating and determining the amount of' feed, and mechanism foractuating the said shafts, together with levers, rods, and bellcrankangle-irons, by which the entire machine may be thrown out of gear orthe conveyer on either side independently caused to cease operation, asset forth.
